fix broken links (#239)

## 💸 TL;DR
<!-- What's the three sentence summary of purpose of the PR -->

| Link | Before | After |
| --- | --- | --- |
| Redis → TxClientLike (two occurrences) | `/type-aliases/TxClientLike`
— 404 | `/interfaces/TxClientLike` — valid reference |
| Redis → Compression | `#compression-experimental` — missing section |
`#migration-example`, renamed “Migration Example” |
| Games and Mod Tools → Quickstart | `/docs/quickstart/` — HTTP 404 |
`/docs/quickstart` — valid URL |
| Redis → Errors inside a transaction |
`/develop/interact/transactions/` redirected and lost the section anchor
| `/develop/using-commands/transactions/#errors-inside-a-transaction`
goes directly to the section |
